Abstract

The invention discloses an omni-directional tide observation system under the well, which relates to a tide observation system. In the invention, a system mainframe box (B) on the ground (A) is connected with an instrument body (E) which is arranged in a protecting pipe (D) of a drilling well through the transmission cable (C). The structure of the interior of instrument body (E) comprises a hoisting hole (1), a pressing spring (3), a supporting pole (4), a location device (5), a ball head joint (6), a circuit unit, a gravimeter (9), a clinometer (11), a primary leveling device (12) and a precise leveling device (13), which are connected in turn from top to bottom. The invention integrates the gravity instrument with the clinometers, which is put under the well; the gravity solid tide in the upright direction and the horizontal solid tide in two directions can be observed synchronously at the same time and place; the invention provides reliable, precise and continuous observation data; the invention can also be used in a general cave with the qualification of a triangle base.

Description

technical field

[0001] The invention relates to a tide observation system, in particular to a downhole gravity and inclined solid tide comprehensive observation system. Background technique

[0002] In the study of planetary solid tides, in order to measure the component of the tidal force at a given point, three instruments must be placed along the three axes of the local reference system, and a gravimeter must be placed in the direction of the vertical line pointing to the zenith to measure the tidal force. The vertical component is the gravitational solid tide; inclinometers are installed in two horizontal directions in the horizontal plane to measure the north-south and east-west components of the tidal force, that is, the inclined solid tide.

[0003] At present, most of the three components of solid tides are observed with gravimeters and inclinometers at home and abroad. In this way, the vertical component of tidal force is observed more or less at a given point, but ...
